In recent years, a whole new generation of cargo vessels have begun sailing the oceans of the world at speeds that in the past were confined to fast passenger liners. They are known as container ships, monsters with powerful engines developing up to 90,000 horse power. These ships are primarily important due to the fact that the container method of transporting goods has revolutionised maritime cargo carrying because of the speed at which they can be loaded and unloaded when they arrive at a port specially equipped to handle the containers. These containers look like giant building blocks and are made to a standard size.
